I have called in and asked this question to Mark without a definite answer. I am getting a P304 code which is different from the P300 code and the dealer did a "REPROGRAM ECU PER TSB 05-13-003 FOR MISFIRE CODE". Will this overwrite my TT mail in flash? My understanding is that this is a sperate part of the ECU. I have not driven the car hard enough yet to feel a difference in power.

Also Mark you said that if the dealer flash is done that you will be unable to do another flash to the ECU. Is this true?

Thanks!

 

i'm curious also

 

It WILL overwrite the TT flash. and YES, you can get it flashed again. We have done it several times.

 

I guess thats how it has to be. I can handle that. Thanks for your quick reply. I am calling TT to see about getting this done.

 

Not to ruin your day but I've also heard that a stock ecu can not be reflash after getting the P0300 code done. I hope I'm wrong but I consider my source pretty solid.

 

They told me I need to send it back to them so then they would send it to Japan to get it flashed there where they can compensate for this code. It sounds worth it, but I wonder how long the wait will be.

Turbotrix - Please correct me here and add all this information in this post so others with the P0300 reflash and your Tuning flash can benefit from a reflash. Thanks!

 

You are right.. once the dealer reflashes your ecu for the P0300 fix it does overwrite our flash + makes us unable to retune it... we can however send it out to japan which usually doesn't take longer then a week or 2.. you would just have to pay shipping from us to the makers of the flash software.. they then forward it. You will not have to pay for the flash all over again.

im planning to get flash from TT when i go to jersey, mines stock, but i got dealer reflash for po300 code, will you able to TT flash it?

 

What part of "once the dealer reflashes your ecu for the P0300 fix it does overwrite our flash + makes us unable to retune it" don't you understand?

 

but i never had a TT flash. if i do, it will be my first time and im just saying my ecu was reflashed for po300, get it?

 

Mike,
Could you please PM more info on this. I am very interested.
